Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149450, here are decompositions:

31 + 149419 = 149450
73 + 149377 = 149450
79 + 149371 = 149450
109 + 149341 = 149450
127 + 149323 = 149450
163 + 149287 = 149450
181 + 149269 = 149450
193 + 149257 = 149450

Showing the first eight; more decompositions exist.
